Sadie Robertson told E! News that she had modeled previously at small events in her native Louisiana. But, as she noted, New York Fashion Week was "a whole new ball game."

The 16-year-old Sadie Robertson is clearly growing up, but that does not mean her father, Willie, is ready to completely let her go. The teenager admitted to Fox News that the dresses she designed needed her father's approval.

"Me and my mother and my grandma went to Sherri Hill's place and we all picked out 'daddy-approved length,'" she said. "She also added a couple inches to some that we loved but weren't modest."

It's no surprise that Sadie's designing career became a family affair. The Duck Dynasty stars became famous for their group duck-call business. In fact, this emphasis on family is one of the reasons Sadie's mother, Korie Robertson, likes her daughter's partnership with Hill.

"We're so proud and so happy about the partnership with Sherri Hill," Korie Robertson said. "She's been awesome. And they're a family business like we are, so we feel really great."

Sadie Robertson also recently spoke to Fox News about the controversy surrounding Miley Cyrus. The latter teen star made headlines for a raunchy twerking performance at the MTV Video Music Awards. Then, earlier this week, she appeared nude in the video for her latest single, "Wrecking Ball."

"My family has been praying for her [Miley Cyrus'] family," Sadie Robertson said. "We feel very bad for her because we know how entertainment can get wrapped up in your head. We try to stay strong as a family. We just pray that their family comes back together."

And no, you will not see the Duck Dynasty star twerk anytime soon.

"I would never twerk in public," she said. "It is not modest to me but for the girls out there that do, it's their decision."
